Källor: Israel planerar stor markinvasion i Libanon

The Israel-Lebanon escalation news introduces a classic geopolitical risk-off shock into a technically vulnerable S&P 500 already declining -4% over 12 months and sitting ~5% below its 5-year peak of 6978. The recent price sequence (6795→6740→6781→6775→6672→6632) confirms accelerating selling pressure in March 2026 prior to this catalyst, meaning the index lacks the momentum buffer that absorbed prior geopolitical shocks in 2023-2024. Monthly volatility at 3.56σ implies a 1-sigma downside move targets ~6396, while a 2-sigma event pushes toward 6160-6200 — a region of strong structural support. Historical precedent shows Middle East ground invasions generate a 2-5% initial equity drawdown within 5-10 sessions, with recovery dependent entirely on conflict containment; an Iran proxy escalation materially extends the drawdown timeline and magnitude. ⚡ DEEP SONNET: Short bias on any intraday bounce toward 6650-6680 resistance (prior support turned resistance); alternatively, confirm break below 6580 on volume before initiating. Avoid chasing initial gap-down open — geopolitical trades reward patience on first-day overreaction. | TP:5.5% SL:2.8% | 10-20 trading sessions (2-4 weeks) | Risk:MEDIUM — Geopolitical risk is real and structurally amplified by pre-existing technical weakness, but direct US economic transmission is limited unless Strait of Hormuz/Iranian escalation materializes. Oil spike and safe-haven rotation are the primary transmission mechanisms. Asymmetric risk exists because the index is already wounded; a 3-5% geopolitical shock on top of existing -4% 12m trend creates compounding bearish narrative. Upside risk: conflict de-escalation or US diplomatic intervention triggers sharp short-covering rally. | Sizing:CONSERVATIVE
